Pull the blades and the lower cups will come off. They catch overflow grease, and if it has been greased properly, they should have alot off goo in them. Pull the top bolt on the gearbox and oil should seep. If it has been lubed well, there should be no problem I think.
Also check the rollers and see if they seem loose on their spindles. Could need new rollers.
ONce you'e done all that, go buy a 60"! /forums/images/graemlins/cool.gif
